ELECTRIC .HAND LAMP.

Application filed August 15, 1921. Serial No. 492,281.

To all whom it may concern:

Be it known that I, Davn) PEPPER, citizen'of the United States of America, and resident of the city and county of Philadelphia, in the State of Pennsylvania, have inventedcertain new and useful Improvements in': Electric'Hand Lamps, of which the following is a true and exact description, rcfer eneebeing had to the accompanying drawingi, which form a part thereof.

invention relates to electric lamps of the and lamp or flashlight type and has for *itsobject to provide a lamp of this kind of exceedingly simple and effective construction particularly with relation to the switch mechanism by which the battery is connected and disconnected from the lamp. Another object of my invention is to provide 'in'a convenient and secure place in the casing a reservoir for extra lamps and the third object is to provide simple and effective means for changing'the focus of the reflector with reference to the lamp.

' The nature of my improvements will be best' understood as described in connection with the drawings in which they are illus trated and in which- Figure 1 is a sectional elevation of a hand lamp provided with my improvements. '-.-Fi'gure 2 is a sectional elevation of the upper art of the lamp taken on the line 2 2 0 Fig. 1. v

'Figure 3 is a'section on the line 3-3 of Fig. 1 looking upward igurefl is asection on the line H of Fi 1 looking upward, and

- igure 5 is a sectional elevation of the upper part of the lamp, showing certain modifications.

A indicates the lamp casing which, as shown, is formed with a threaded lower end A and a threaded upper end A. Through the upper part of the casing are formed rectangular openings A A for the passage of the switch actuating bar. 13 is a screw cap closing the lower end of the casing and supporting the spiral spring indicated at b. D D are battery elements having, as shown. contact extensions D D. E is a flared end piece having a threaded portion E by means of which it screws on the outside of the threaded portion A of the casing and having at its upper end a threaded portion E on which screws the cap piece F having an inwardly turned flange F the function of which is to grip the re flector and the lens, not shown. against the upper end of the'ca-p piece E. G is the re flector having-a flange'G"which rests on the'top of the cap piece'E, as shown, and having at 'its base the .circular recess G through which the lamp-can be passed. H is Ia lampyholder having an upwardly extending threaded, flange H which screws into the threaded portioxi- A of the casing. This lamp holding-disc is also formed with a downwardly extending threaded flange H 2 into which screwsth'e socketL' of the lamp indicated at-L.- =I a'disc of insulating material which,.,as shown-inFigs. 1 and 2, is curedto theflam holder by a nut J and from which de end 0 1 '5 indicated at K K adapted t'o':-ho d in-p lazce spare lamps,.as best shown intFig. 3i {M;is aiplate of insulating material secured50n the: inside of the. easing and ;M"a covering plate of insulating material ;:both plates haverectangular openings 'formed throu'gh them inregistrywith theiopening A on one? side of :thecasin'g and between them is 'clamp'ed the metallic platex'N having.extending from its upper end the spring contact tongue N, the-end of which isbentrso' as to form an angle N with "an :upwardly .extending arm N which, when forced upward, comes in contact with the lam 'base. From the lower end of the plate extends the spring contact arm N, the end N? of which rests in contactrwith the sliding bar indicated at O. :This-bar-extends through the casin as shown and is formed on its upper'sur ace with the angular recess 0' which is adapted to receive the angular ortion N of the contact'spring when the ar is in the posi= tion shown in Fig. 1. The bar is also preferably formed with a transverse detent groove 0 on its upper face, and with a transverse groove 0 on its lower face on which rests the end N of the contact spring N The construction I have described involves also the provision below the lam holder and the top of the upper battery of a chamber AA which serves as a reservoir for spare lamps.

In the construction shown in Fig. 5 the lamp L has its socket L screwing into a threaded flange formed at the bottom of the reflector, here indicated at g, said reflector being formed with a flange g which rests directly on the top of the casing, here indicated at a, and is held in place by a flange of a screw linkf which sorews-on=-the,out-- side of the threadedend a -of the casing. In this construction the insulated spare lamp holder I is. shown as screwingon the,

threaded flange of the reflector which is indicated at g; in other respects theconstnucw tion here shown is. similar to that of the other figures.

Referring to the construction of Figs. 1v

t04, the lamp holder is secured ill-the endof the-casing by screwing into the threaded end thereoflthe lamp screws into the socketof the holder as shown, and the insulated disc I is secured on the under side of the lamp holder as described and-spare lamps inserted in the clips K find ample room .in

the chamber AAone lamp being held-oneach side of the sliding bar.(), as is best shown in Fig.3. The adjustable head E is screwedon the outside'of the easingiend and the reflector- G and the lens; not shown, are

secured in plane bythe-fiangedE ring- F and obviously 'by screwing the holder: E in or out-the 'focusof the reflector. :withreference 1 to the lamp can beadjusted at WllLt The contact: springs, formed as described,v

are secured to the side: of the casingand the sliding bar 0 inserted until its detent. slot Oris engaged by the. end N of the spring arm N, The insertion-of this bar at first movementof the slidingbar-O will press the switch up into contact with the lamp.

The spring bar N rests in permanent contact with'the contact extension D" of the Lip-- per battery as shown and the battery is held in place between this spring and the spring C so as to protect the lamp as a whole from sudden jar which might tend to disrupt or disorder its parts.
